I have a buddy who would rage quit when he dies in games, then rant about how there’s no advantage for skilled players and, “this game is all luck!”
He was exceptionally good at strategy games. Back in the days of Warcraft II, he would spend days writing down exact second-by-second instructions for building the perfect base to dominate the map. (“Dedicate 4 seconds to starting this building, the next 9 seconds are needed to harvest this resource, then 13 seconds to start recruiting 4 infantry,” etc.).
By the time I had made maybe 3 buildings and a few peons harvesting resources, he was already invading my base with a massive army. He probably could’ve gone pro, if esports leagues were a thing in our youth.
But he was a terrible loser. If his strategy didn’t go to plan, he would throw a fit about the game cheating and being all about luck instead of skill.
